Chris, Eric - We finally got around to upgrading (on site) our very first 12 port DC switch we've had in service and started reading voltages via SNMP. While on site, I logged into the GUI and saw voltage was lower than expected. After measuring at the lugs on the switch, we were seeing a .25v drop between the GUI and volt meter. I remember reading months ago about possibly adding correction for this?

I also would like better voltage resolution. Down to the hundredth would be much more usable than the tenth IMHO and should be standard. Is this something that can be easily changed in an upcoming release?

Thanks guys!

My first thought is whether there is reverse polarity diode protection cuz if there is, depending on where the voltage is sampled, there could be a voltage drop across the diode.

We are considering a calibration routine for the DC switch models eventually but it may be awhile before we attempt to implement this as our primary goal is to first get all current functions bug free.

I "doubt" we will pursue 100th of a volt precision as it really makes little sense as it will fluctuate too much with variable loads as radios draw a wide range based on what they are doing. For instance a Rocket M5 will vary between less than 3 watts to over 12 watts when it transmits.

Any possibility of getting the resolution down to the hundredth instead of tenth of a voltage?
